' HARRY W. YOUNG, OF CHICAGO, ILLINOIS.

FUSE-HOLDER.

To all whom it may concern:

Be it known that I, HARRY W. YonNc, a citizen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inFusesHolders, of which the following. is a specification.

My invention relates to improvements in electrical fuse holders and hasfor its. object the production of a device of this character which willbe so. constructed that a. fuse may be readily and easily arrangedtherein and as. expeditiously detached therefrom when desired.

A further object is the production of a fuse holder of the charactermentioned which witl be durable and economical in construction andabsolutely safe in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter fully described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification and in which Figure 1 is aperspective view of a fuse holder embodying my invention, thehingarrangement, it will be seen that the base of the head of the screwis inaccessible and so edly connected parts of the holder being shown inopen ositions, Fig. 2 is a top plan view of the holder, Fig.3is acentral longitudinal section of the holder, Fig. 4: is a transversesection taken on line w-m of Fig. 3, and Fig. is a plan. view of one'ofthe fuses adapted, for use in conjunction. with.

the holder.

The preferred form of construction, as illustrated in. the drawings,comprises a tubular body which is formed of insulating material, fiberbeing preferably used in this connection. Said body is cylindrical inform and is constituted of two similar half parts 1, each of which issemi-circular in cross-section. The central. portions of the parts 1.arelined within with a layer of noncombustible material, asbestos .beingpreferably used, this non-combustible layer of lining serving to protectthe body 1 against fire.

Provided at the extremities of the body of the holder are metallic caps,each of which comprises two similar half parts 3, said cap parts 3 beingsecured to the body parts 1 by flanges 4 which are formed at the edge ofsaid cap parts, as shown "in the several views, said flanges embracingthe adjacent edges of said body parts. The cap parts 3 Specification ofLetters Patent.

parallelly extending portion 9. at. theinner end of each of the ears 8is a screw- 10, the head of which projects through Patented Feb.17,1914.

at one end of the body are hingedly connected at 5 so as to permit thecomponent parts of the holder being swung to positions indicated in Fig.1, in order to permit of ready insertion or removal of a fuse, ashereinafter described. One of the cap parts 3 at the opposite end of theholder is provided with a spring tongue (3, the slotted free end ofwhich is adapted to engage with .lug 7 provided upon the correspondingcap part 3 in order to releasably lock the parts of the holder in closedposition, as clearly shown in- Fig. 3'.

Formed upon each of thecapparts 3 at the respective ends of one of thebody parts "1 is an inwardly projecting ear 8, the inner end of which isbent upon itself to form a Provided a perforation provided in the ear,the stem of said screw passing through an alining :perforation providedin the portion 9, the head of the screw being provided at its base :withan annular flange 11 which is interposed between portions 8 and 9 inorder to :constitute a swivel connection between the screw and thesupport therefor. With this that in. use, the possibility of inserting arail or other article thereunder to serve as a fuse and thereby defeatthe purpose of the 4 fuse, will be precluded. Threaded upon the lowerend of each of the screws 10 is a nut .12 which is held against rotationby means of depending flanges 13 provided upon the opposite edges ofcars 8. p

In use the fuse 14 is held in position in the holder by inserting thebifurcated ends 15 thereof between the end-portions 9 of the supportingears 8 and the nuts 12, clampingof said fuse in position being effectedby rotating the screws, as will be readily understood. Transverselyextending partitlons 16 of non-combustible material, preferablyasbestos, are provided within each of the body parts 1 which are soarranged that, when the body parts are in closed position, an inclosedchamber will be formed about the central or weakened portion of the fuseand so that when the blowout or fusion occurs, the incidental sparkswill be prevented from escaping, thereby averting accidents which mightotherwise result. 1

holder, it beingclear, that when the holder is in open position, thescrews 10 will be readily accessible for releasing the spent fuse andfor securing a new fuse in its place.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofVariation and modification without departing from the spirit of theinvention.

I, therefore, do not wish to be limited to the precise details ofconstruction set forth but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Let tors Patent, is

1. A fuse holder comprising a hollow body, inwardly projectingsupporting arms at the ends of said body, the inner ends of said armsbeing bent back upon themselves;

screws swiveled in said arms and having heads provided with enlargedbase portions, the base portions of the heads of said screws beinginterposed between said arms and the bent back portions thereof, and oneof said arm portions being provided with an opening somewhat smallerthan and adapted to receive the corresponding screw head; and nutscooperating with said screws for engaging the ends of a fuse arranged inthe holder, substantially as described.

2. A fuse holder comprising a hollow elongated body of insulatingmaterial, said body being divided into two separable parts; means formedof conducting material provided at the extremities of said body partsfor hingedly securing said parts together; inwardly projectingsupporting arms on v said last mentioned means, the inner ends of saidarms being bent back upon themselves; screws swiveled in said arms, the

base portions of the heads of said screws being interposed between saidarms and the bent back portions thereof; and nuts cooperating with saidscrews for engaging the ends of a fuse arranged in the holder,substantially as described.

3.'A fuse holder comprising a hollow elongated body of insulatlngmaterial, said body being divided into two separable parts; means formedof conducting material provided at the extremities of sand body partsfor hingedly securing said parts together; inwardly projectingsupporting arms on said last mentioned means, the inner ends of saidarms being bent back upon themselves; depending flanges on said arms,screws swiveled in said arms, the base portions of the heads of saidscrews being interposed between said arms and the bent back portionsthereof; and non-rotatable nuts threaded on said screw for engaging theends of a fuse arranged in the holder, substantially as described.

4. A fuse holder comprising a hollow elongated body of insulatingmaterial, said body being divided longitudinally into two separableparts; a hinge connection between said parts; inwardly projectingsupporting means formed of conducting material provided at the ends ofsaid body; means at the inner ends of said supporting means forfastening thereto the respective ends of a fuse arranged in said body;and transversely extending partitions of non-combustible material insaid body parts adapted, when said body parts are in registration,'toform a central chamber in said body, substantially as described.

5. A fuse holder comprising a tubular body of insulating material; alayer of noncombustible material lining the inner side of said body,said body consisting of two similar parts substantially semi-circular incross-section; caps of conducting material and of corresponding-formprovided at the extremities of said body parts; a hinge connectionbetween the caps at one end of said body; means upon the caps at theopposite end of said body for releasably locking said parts in closedposition; an inwardly projecting supporting arm provided on one of saidcaps at each end of said body; means at the inner ends of said arms forreleasably fastening thereto the respective ends of a fuse arranged insaid body; and transversely extending partitions of non-c0mbustiblematerial in said body parts adapted, when said body parts are inregistration, to form a central chamber in said body, substantially asdescribed.

Intestimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses:
